2FA Authenticator App is a simple and free application for Two Factor Authentication (2FA) which generates Time-based One-time Passwords (TOTP). 2FAS App helps you protect your account from hackers by adding an additional layer of security. With the 2FAS Backup system, you can store all your Keys in the cloud and access them when needed. In case you lose or damage your phone, you simply install 2FAS App on your new device to get access to your Keys.

For your convenience, you can either use a QR Code or enter your secret key manually.

Why 2FAS APP is the most secure and private Two Factor Authentication app?

-Two Factor Authentication
2FA doubles the account's security by requiring a regular password and a Time-based One-time Password (TOTP). 2FAS App generates TOTP on the user’s device.

-2FAS Backup
We are developing a remote backup service (RBS) function that will allow you to store service keys in a secure 2FAS Backup based on a cloud and recover it if you lose your phone. This feature will also allow you to generate codes on different devices (cross-device sharing).

-Authorize with Touch ID or Face ID
Confirm your identity with the application using Touch ID or Face ID and generate one time tokens required to log in to your online accounts.

-Sync across devices
Once configured with an online account, the application works efficiently on various mobile devices and allows you to log in from several devices at once.

-No password stored
The application generates Time-based One-time Passwords (TOTP), stored on the user's phone without internet access. This solution dramatically increases login security.

Exactly What I Wanted!

I was getting fed up with all of the cheap React Native and Cordova 2FA apps. Was about to write me own, how hard can it be? Did one more search to see if I could find something that was native iOS and supported iCloud, and tried this app out. IT’S EXACTLY WHAT I WANTED! To the point, not always trying to sell me stuff, high quality native iOS, simple, and stores data on iCloud instead of some mysterious “just trust us 😉” third party service. I have only a single gripe, but extremely minor. Could you please make the 2FA codes collapse to hide until clicked on, and style each cell in the UITableView to be more like the bubble tiles seen on the App Store’s home view? You’re awesome!

Update request. Read the reviews and let us know how things are going.

The reviews were perfect. Pointing out issues a new client will have and then addressing the issue turns this into a help feature. People need full service. The world that shunned technology is running this way. Let this be a lighthouse app. One that offers assistance to all the crazy people that don’t know that their adhd is preyed upon by ads. Showing the progress of the people and the issues they were having. Showing us the value of a place where sharp people are drawn to shore safely by shedding light on impending danger. I’m a flesh and blood, living, breathing human being. That means I’m weird, confused, and making progress because I made it here. For some people, this is progress. I am some people. I went ahead and shared the rough draft. However, this is my review of the comments since I haven’t decided on an app yep. Thanks in advance;) Give us an update of what can we look forward to in the wake of emerging technologies. Where can we get in front of the wave? Web Surfing in 2022.

Has almost everything I want in an 2FA app

This app has a nice UI, is intuitive and easy to use, and the file backup is a nice addition that I’ve only ever seen on computer apps or browser extensions. The biggest issue I have with it is that when I turn on Face ID, it doesn’t quite ask for the Face ID every time I open the app. If I want a protected app that asks for Face ID at all, it defeats the purpose for me if it doesn’t ask for my face even AFTER I TURN THE PHONE OFF AND TURN IT BACK ON. This is one of the hugest reasons that I deleted the app and opted for another authenticator app. The other reason is that I wish there was an option to omit an icon/badge/label altogether. This is picky, I know, but I either want every entry to have a logo icon or I want none of them to. And this app doesn’t have the ability to get rid of the icons.

Developer Response ,

Hi, thanks for the review. I'll forward the idea about no icons to the team, and I'm sure we will have it in future updates. Now the FaceID. If you use it to unlock your phone, it authorizes our app to unlock because your phone knows that you still have it in your hand and doesn't need additional unlocking. When FaceID unlock actually happens on our app, it's so fast that most of the time, it's almost unnoticeable. So it's Ios that authorizes our app, and we can't change the Ios system and fight against it is not wise. Please reconsider coming back to us! 😊
